Physiological Adaptations (HSC SSCE Biology): Flashcards

Body function changes helping organisms survive in environment

Lower freezing point to prevent ice crystal damage in cells

Lose leaves and enter dormancy (reduced metabolic activity)

Flowering in response to low temperature exposure

Plants adapted to saline environments

Increase water in vacuoles to dilute accumulated salt

Transport salt to bladder cells on leaf hairs that burst

Excrete highly concentrated urine to reduce water loss

Arterial blood warms venous blood, reducing heat loss at feet

Reduced metabolic rate lowering body temp in hot environments
